The best time to go to Corniglia is during the shoulder seasons, specifically from April to early June or in September and October.These months offer pleasant weather for hiking and exploring without the intense heat and large crowds of the peak summer months. You'll find the footpaths, like the famous Sentiero Azzurro connecting the Cinque Terre villages, are more comfortable to navigate, and local restaurants and shops are fully open. The sea is also warm enough for swimming in late spring and early autumn.For those looking for a quieter experience, particularly couples, visiting in late April or early May provides beautiful spring blooms and a more relaxed pace. You'll have an easier time securing reservations at popular eateries and enjoying the stunning coastal views without feeling rushed.
